Separation course

A four component system is being flashed using a flash drum. The flash is carried out at 1atm and 60C. The given mole fractions of the feed stream are z1=0.25,z2=0.40,z3=0.20, and z4= 0.15. Vapor pressure can be estimated using the Antoine equation: lnPi=AiTCiBiTinK,andPinatm The parameters for the Antoine equation are: Write a MatLab code that can be used to estimate the dew point TD, buble point TB, and compute the composition of both vapor and liquid flashed at the specfied temperature and pressure (60C. latm) using Rault's law. Test the code with the system given above. Detemine the effect of pressure on the vapor fraction of the mixture (i.e. compute V/F at different values of P=1..5 atmospheric pressure)
